5 which clasp is of one piece ofmetal and is adapted for receiving adecorative design or configuration,

It is an object of this invention to provide a snap clasp which is madeof a single piece of metal, has a part formed to receive a decorativedesign, and a part adapted to tend to hold the. parts of the clasp inthe closed a position with respect to each other.

Other objects and advantages of the invention will appear fromreadingthe following description of an illustrative embodiment of theinvention and from a study of the drawing showing the same; and theinvention also consists in the combinations and arrangements of partsset forth in the appended claim.

In the drawing, which illustrates one form of the invention and amodification thereof;

Figure 1 is a top plan view of a snap clasp connecting a string ofheads, the latter shown in part; g j

Figure 2 is a side elevation view; of, the parts shown in Figure 1; I

Figure 3 is a bottom plan view of the same witih one end of the stringof beads unclasped; an 7 Figures 4 and 5 are, respectively, a sideelevation view in part section and abottom plan view of a modified formof the clasp of the invention. 3 Y

In all the above described figures of the drawing like characters ofreference are used throughout to indicate corresponding parts.

Referring now to Figures 1 to 3 of the drawing the reference character 1indicates a flat body of metal which is oval in plan and has one end 2which turns under the body 1 and then widens out to form the generallyoval under-body 3 which lies parallel to said body 1. At its free endsaid under-body 3 has an offset portion 4 adapted to receive thecorresponding end 5 of said body 1, which end 5 is curved-downward andthen around in that direction, The oval h pe f body 1 and under-body 3provides that the structure has suflicient strength for its'purpose andthat the ends 2 and 5 are small enough for receiving connecting meanssuch as the rings 7 and 8 on the strin of beads 9. The oval shape ofsaid body 1 and also of under body 3 if desired) further provides asurface for receiving a decorative design 10 either in applique, enamel,engraving or-other form to conform with the decorative plan'of the wholejewelry article. It is to be understood that the body 1 is not limitedto the oval form shown but can be diamond shaped or otherwise variedwithout departing from the objects and purposes of the invention toclasp structure for holding it in the closed relation.

In Figures 4 and 5 of thedrawingamodified form of the clasp of theinvention is shown, which form, inaddition to the parts above describedfor Figs. 1 to 3, has a closing spring 11 preferably formed integralwith provide a clasp which is thin from front to I back, which is wideand consequently adaptthe rest of claspby punching a tongue 11, 7

from said under-body 3 and bending it so that in the closed position ofthe clasp said spring 11 will bear against the inner face of said body 1and tend to hold said offset portion 4 in seated relation on saidinturned'edgefi of said end 5; This further contributes to theunderstood that various omissions, substitu- 9 tions and changes in theforms and details of the device illustrated and in its useand,operation'may be made by those skilled in the art without departingfromthe spirit of the invention.

Having thus described my invention, what I claim and desire to secure byLetters Patentis:

A jewelry clasp comprising, a substantially'flat oval shaped under-bodyhaving an inwardly ofi'set portion at one end, a fiat oval shaped mainbody having reduced end portions bent over in spaced relation to saidmain body, one of said end portions being formed; integ al, with. an endof said under body and acting to urge the offset portionof saidunder-body outwardlyagainst the other reduced end portion of said mainbody, said latter reduced end portion forming a stop for said underbodyand lying Within the outer plane of said under body so as to. servesubstantially as a continuation thereof and a tongue shaped springstruck inwardly from said under-body and pressing against the inner sideof said main body, said spring acting to as- 1 sist in urging the offsetportion of said underbody against said latter reduced end portion ofsaid main body.

In testimony, that I claimthe invention set forth above Ihave hereuntoset my hand 15
